In my experience with a T420 U12.04b2 the SDHC card appeared. However, had (different) problems https://bugs.launchpad.net/ubuntu/+source/linux/+bug/975305.

In U12.04b2 I see it appear and can read/write although I'm not convinced reliably read-write and have problems with dd. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/978929 Title: [Lenovo Thinkpad T420] SD Card-reader non functional To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/978929/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
